Daniel writes: A few bugfixes for serious stuff and regressions. Highlight is the reinstated hack to keep the i915 backlight on when running on an optimus machine, this prevents black screens especially with some radeon muxed platforms. And the patch to quiet dmesg on Linus' old mac mini ;-) * tag 'drm-intel-fixes-2013-08-08' of git://people.freedesktop.org/~danvet/drm-intel: drm/i915: do not disable backlight on vgaswitcheroo switch off drm/i915: Don't call encoder's get_config unless encoder is active drm/i915: avoid brightness overflow when doing scale drm/i915: update last_vblank when disabling the power well drm/i915: fix gen4 digital port hotplug definitions
It takes an unsigned value. This happens not to blow up on 64-bit architectures, but it does on 32-bit, causing drm_calc_vbltimestamp_from_scanoutpos() to calculate totally bogus timestamps for vblank events. Which in turn causes e.g. gnome-shell to hang after a DPMS off cycle with current xf86-video-ati Git.

Some more radeon fixes. Mostly dpm and uvd fixes. Fixes hangs with dpm on more rv6xx asics, and fixes suspend and resume with UVD. * 'drm-fixes-3.11' of git://people.freedesktop.org/~agd5f/linux: drm/radeon: make missing smc ucode non-fatal drm/radeon/dpm: require rlc for dpm drm/radeon/cik: use a mutex to properly lock srbm instanced registers drm/radeon: remove unnecessary unpin drm/radeon: add more UVD CS checking drm/radeon: stop sending invalid UVD destroy msg drm/radeon: only save UVD bo when we have open handles drm/radeon: always program the MC on startup drm/radeon: fix audio dto calculation on DCE3+ (v3) drm/radeon/dpm: disable sclk ss on rv6xx drm/radeon: fix halting UVD drm/radeon/dpm: adjust power state properly for UVD on SI drm/radeon/dpm: fix spread spectrum setup (v2) drm/radeon/dpm: adjust thermal protection requirements drm/radeon: select audio dto based on encoder id for DCE3 drm/radeon: properly handle pm on gpu reset
The smc ucode is required for dpm (dynamic power management), but if it's missing just skip dpm setup and don't disable acceleration. Should fix: https://bugs.freedesktop.org/show_bug.cgi?id=67876 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
The rlc is required for dpm to work properly, so if the rlc ucode is missing, don't enable dpm. Enabling dpm without the rlc enabled can result in hangs. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
